Code:U1000Modules:Audio Amplifier, BCM, DDM, DRR, DSM, EBCM, ECM/PCM, GBCM, HVAC Control Module, IPC, PDM, Radio, RWSCDescription:Class 2 Data Link Malfunction

There is a DTC lookup sticky at the top of the forum. Sounds like a harness problem to me.

thanks sparky,
which of these would cause it not to start. keep in mind, all was fine then it just died. i know to check the ecm but are any others vital to a start or idle.

I don't know, but maybe these were set when you removed the edge? I think that code shows a total failure in communications, which would have happened when you removed it. (I have never messed with the harness so I base that on what I have read.) Make sure you got the harness back together, did not bend any pins, etc.

I lot of people would proably say disconnect the batteries for 12 hours or so and see if everything resests.

Hopefully some of guys with Edge problems will chime in.
